Håkan says:
‘Working with micromolluscs requires great care, patience, and persistence, as they are so tiny. But despite being only about 2–3mm in size, they have a beautiful and elaborate structure. 

This shelled mollusc was found in a marine water sample collected from a fish farm in Stockholm. By using fluorescence microscopy with ultraviolet light, the microalgae and cyanobacteria that grow on the surface of the shell are autofluorescing in red and orange, while the shell is blue.’
